IRON CASTING.

Specification of Letters Patent.

Patented June 18, 1918.

Application filed October 3, 1916. Serial No. 128,599. i

To all whom it may concern:

Be it known that I, WILBERT C. SCHADE, a citizen of the United States,residing at Meadville, in the county of Crawford and State ofPennsylvania, have invented new and useful Improvements in IronCastings, of which the following is a specification. I

y invention relates broadly to iron castand more particularly toreinforced iron castings. One object thereof is to produce iron castingswith metal reinforcement for general purposes, railway tie-plates.Another object is to pro vide a railway tie-plate composed of cast iron.Other objects will appear hereinafter.

Referring to the accompanying drawings, Figure I is a vertical sectionshowing a tieings plate made in accordance with my invention andassembled with a rail, a portion of a tie, and spikes; Fig. II, a planview of the tie-plate with a portion broken away to show the metalreinforcement incorporated therein; Fig. III, an edge "iew of thetie-plate; and Fig. IV, an edge view of the tie-plate looking at Fig. IIfrom the right.

On the drawings, 1 designates the body of the tie-plate which iscomposed of a flat rectangular cast iron plate preferably having themetal reinforcement 2 incorporated therein at the time the plate iscast. This reinforcement comprises a number of metal wires or rodsarranged in the form of a woven fabric, but it is to be understood thatthe Wires or rods may be differently arranged from the manner shown andthat the reinforcement may be made of various material constructed invarious designs. This reinforcement strengthens the tie-plate so that itwill resist strains and shocks in all directions, and in case the plateshould break the reinforcement would prevent the separa tion of thefragments or the movement of a Copies of this patent may be obtained forlive cent: each, by addressing the Washington, D. 0.

plate with the fla but particularly, for

erly seated on the tie plate.

porl-tion of the tie plate from beneath thev ra1 I provide the tie-platel with suitable spike holes .3 near opposite edges thereof, the opposingsides ing spaced apart a distance equal to the flanges 4 of the rail 5,which rests on the tieges 4 just reaching the holes 3.

On the upper face of the tie-plate I arrange the rib 6 so that it willbe engaged by one of the rail flanges when. the rail is pro The rib 6 isinterrupted at the spike holes 3. I have shown this rib for only onerail flange, but a second rib may be placed near the other edge of theplate for engagement withthe' remaining rail flange, if desired. Thetieplate has at the outer edge of each spike hole 3 a lug 7 arranged tostand opposite the rail flange and prevent the spike 8 from bending awayfrom the flange.

I provide the lower face of the tie-plate with a number of wedge-shapedribs 9 which are arranged transversely of the rail and adapted to extendinto the tie 10 as shown on Fig. I. These ribs prevent any creeping ofthe tie-plate in any direction onthe tie.

prefer to place these ribs near the'edges of the tie-plate and have oneat each side of each spike hole.

Although I have shown and described my invention applied to a railwaytie, it is to be understood that it is applicable to iron castings ofall kinds.

I claim A tie-plate comprising an iron casting of the opposite holesbehaving incorporated therein a metal reinforcement of fabricsubstantially co-extensive With the area of the tie-plate.
